A superconducting magnetic energy storage coil is made from a toroidal ring coil (torus). The coil’s cross-sectional radius is d = 1.5 m and radius of the torus is r = 1.5 km. The torus is wound with N = 175,000 turns and is able to carry a current I = 110,000 A. a) Calculate the magnetic flux density in the torus. b) What is the amount of energy stored in the torus? c) If a city requires 500 MW of power how long can this storage ring of this type power the city in case of a blackout in power generation? Assume there are no losses in the conversion of energy from stored DC to AC energy required by standard grids.
